This document discusses lessons learned from implementing a mobile e-portfolio system called MyProgress at St. George's University of London over the past year. Key lessons include ensuring students feel ownership over their portfolio by giving them power and responsibility to complete required workplace-based assessments (WPBAs). While initial pilots were successful, full implementation revealed a need for students to have control over signing off on all their own WPBAs, rather than some requiring additional clinical or academic approval. Ongoing challenges include changing culture among students and clinicians, as well as providing sufficient wireless access and support for the mobile system.
